1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo explore the relationship between cytochrome P450 2E1 (CYP2E1) RsaI/PstI and DraI polymorphism and lung cancer susceptibility in Mongolian and Han population in Inner Mongolia of China.

methodsCYP2E1 RsaI/PstI and DraI polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism in 64 lung cancer patients, 150 healthy Mongolian and 150 healthy Han individuals. The distribution of genotype and allele frequencies of CYP2E1 RsaI/PstI and DraI polymorphisms were studied.

resultsThe risk of lung cancer was increased in individuals with CYP2E1 (cl/cl) and CYP2E1 (DD) with OR values of 2.431 (95%CI=1.082-5.460) and 2.778 (95%CI=1.358-5.683) respectively (P<0.05). When CYP2E1 RsaI/PstI and DraI polymorphisms were combined, the risk of lung cancer was reduced in individuals with CYP2E1 (cl/c2+c2/c2 and DD+CC) with OR values of 0.233 (95%CI=0.088-0.615, P<0.05). In smokers, the susceptibility to lung cancer was higher in the individuals with CYP2E1 (c1/c1) and CYP2E1 (DD) than in the individuals with c2 and C allele (P<0.05, OR=2.643 and 4.308 respectively). There was no significant difference in distribution of CYP2E1 genotype frequency between healthy Mongolian, Han population and lung cancer patients, healthy controls in Inner Mongolia.

conclusionCYP2E1 (c1/c1) and CYP2E1 (DD) are predisposing factors of lung cancer in population in Inner Mongolia. CYP2E1 (c2﹢C) co-mutation may decrease the risk of lung cancer. Smoking exerts synergetic effect with CYP2E1 (c1/c1) and CYP2E1 (DD) on the occurrence of lung cancer.
